MEAT-CHOPPER.

Specification of Letters Patent No. 28,145, dated May 8, 1860.

To all whom it may concern:

Be it known that I, CHRISTIAN B. BECKER, of WVarwick township, Lancastercounty, in the State of Pennsylvania, have invented a new and improvedcombination and useful Improvements on Chopping-Machines for MinoingMeat, &c.; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the accompanying drawings, making a part of thisspecification, and t0 the letters of reference marked thereon.

Figures 1 and 2 are perspective views, showing one side and as seen fromfront and rear of the machine, with the sey eral parts in place. Fig. 3is a front elevation; Fig. 4, a profile view of the gearing detachedfrom the machine; Fig. a side view of one of the choppers i, with itsupright handle I, hoists ing pulley V, &c. Fig. 6 shows the constructionof the rack and pinion for raising the choppers from the block,adjusting the force of stroke also. Fig. 7 is a side elevation of themachine. Fig. 8 shows'the open ring L, with its strap and bucklecleats 1. Figs. A and B illustrate the raising of the choppers.

The revolving block K, with its cogs M, rests on an upright shaft 8, onan adjustable screw point, this screw passes through a bur in the bedpiece B, of the frame A, A, differing from those in common use only, byhaving a ring L, surrounding the block open instead of entire. Thisopening is drawn together by a strap and buckle Z, to the cleats on thering, so as to overlap each other, thereby made adjustable to theshrinking of the block or its expansion through heat or becoming looseotherwise, as often happens. The horlzontal shaft IV, has its bearingson the top side pieces D, and is provided with a turning handle 72,, abevel pinion X, two or more pulleys U, with lifting pegs V, on each oftheir sides, as also a cog-wheel N, at its opposite end from the handle.The shaft Q, has its bearings on the side pieces C, and supports the flyor balance wheel I on one extremity as also a pinion O, geared into, andreceiving motion from the cog wheel N, on the aforesaid shaft IV. Thereis also an upright shaft m, on a step cl. This step is attached to theinside of the handled side piece of the frame work. The shaft m,supports a beveled cog-wheel -Y, which receives motion from the pinionX, on the aforesaid shaft W, and imparts it to the block K, by means ofa pinion a, on its lower end, being gparled into the cogs M (Fig. 4,&c.) of the b oc A series of four or more choppers z', with theirupright handles I, are prevented from side motions by the cross piece F,with its sliding plate f, f, as also the perforated top piece Gr,through which the rounded ends pass, as they are raised up by thelifting pegs w, 7 and forced down by the spiral springs J, on each.There are also rear support-s shown by t, and n, (Fig. 5).

In order to raise the choppers from the block, a rod in, (Fig 3) ispassed through holes in the ends I, on a level with the perforated top,Gr, illustrated by Fig. B, by turning the handled ratchetpinion, S, itruns the cross piece (in which the pinion has its axis) up, carrying thechoppers, (stayed by the rod K,) with it, in the position Fig. A. Thelower cross piece F, to which the rack R, is attached being stationary,and the rack supports 9, g, slide up and down on the edges of the rack,carried up and down with the upper cross-piece G, as shown in theseveral positions by Figs. A and B. The ratchet pinion has also ahandled bur T. By tightening the same will retain the cross piece G atany desired intermediate point, giving the spiral springs more or lessforce, as may be desirable.

I am aware that machines for like purposes are made embracing theprominent features of this machine, and I do not claim the oogged andrevolving block K, nor the raising pegs and pulleys as these are common,nor the upright choppers with their spiral springs as such,independently considered.

What I claim as my invention and desire to secure by Letters Patent isThe specific arrangement of the adjustable ring L, hoisting rack andhandled ratchet R, r, S for raising the choppers, binding nut and handleT, in combination with the sliding braces g, g, and attached crosspieces F, G, constructed in manner and for the purpose described.
